If you love MitoFlex2 and want to support future updates, buy me a coffee: https://buymeacoffee.com/mitoflex **Transform your runs with adaptive HIIT training that boosts endurance, burns fat, and enhances recovery—personalized to your heart rate!** MitoFlex2 is a Garmin data field for adaptive HIIT training. It adjusts surge and recovery based on heart rate recovery for optimal efficiency and prevents overtraining. Ideal for runners, cyclists, and athletes. ### Why Choose MitoFlex2? - **Adaptive Intensity**: Automatically increases or decreases effort based on your recovery speed—no more guesswork! - **Heart Rate Guided**: Uses HRR (Heart Rate Recovery) to measure true stabilization, promoting better aerobic capacity. - **MFS Tracking**: Monitors Maximum Functional Speed for long-term progress and FIT file logging. - **Customizable**: 20+ settings via Garmin Connect for RPE, watts, durations, feedback, and more. - **Easy to Use**: Simple phases with clear on-screen guidance and optional haptic/sound alerts. ### How It Works (Simple 4-Phase Cycle) 1. **Warmup** (5 min): Prep body and heart. 2. **Surge** (30s): High-effort push. 3. **Reach**: Measure HR stabilization. 4. **Recovery** (45s): Low intensity until recovery. Cycles adapt: faster recovery = harder surges; slower = easier. Train smarter! ### Key Features - Real-time HR monitoring and adaptive logic - Multiple display modes (RPE, Watts, Time) - Pause/resume support during activities - FIT export with session metrics - Supports 193+ Garmin devices - Bilingual (English/Swedish) guidance ### Get Started 1. Download MitoFlex2 from the Garmin Connect IQ Store. 2. Add it to your activity data screens. 3. Customize settings in Garmin Connect for your fitness level. 4. Start training and watch your performance soar! **Pro Tip**: Pair with a heart rate monitor. Track your MFS progress over time. --- ## Svenska Version ### Lås upp din topprestanda med MitoFlex2! **Förvandla dina löprundor med adaptiv HIIT-träning som ökar uthållighet, förbränner fett och förbättrar återhämtning—personligt anpassad efter din puls!** MitoFlex2 är ett Garmin-datafält för adaptiv HIIT-träning. Det anpassar surge och återhämtning baserat på pulsåterhämtning för optimal effektivitet och förhindrar överträning. Idealiskt för löpare, cyklister och idrottare. ### Varför välja MitoFlex2? - **Adaptiv Intensitet**: Ökar eller minskar automatiskt ansträngning baserat på din återhämtning—ingen gissning! - **Pulsstyrd**: Använder HRR för att mäta sann stabilisering, främjar bättre aerob kapacitet. - **MFS-spårning**: Övervakar Maximum Functional Speed för långsiktig utveckling och FIT-fil-logging. - **Anpassningsbar**: 20+ inställningar via Garmin Connect för RPE, watt, varaktigheter, feedback och mer. - **Enkel att använda**: Enkla faser med tydlig skärmvägledning och valfria haptiska/ljudvarningar. ### Hur det fungerar (Enkel 4-fas-cykel) 1. **Uppvärmning** (5 min): Förbered kropp och puls. 2. **Surge** (30s): Högansträngning. 3. **Reach**: Mät pulsstabilisering. 4. **Återhämtning** (45s): Låg intensitet tills återhämtning. Cyklar anpassar: snabbare återhämtning = hårdare surges; långsammare = lättare. Träna smartare! ### Nyckelfunktioner - Realtids-pulsövervakning och adaptiv logik - Flera visningslägen (RPE, Watt, Tid) - Paus/återuppta-stöd under aktiviteter - FIT-export med sessionsmått - Stöder 193+ Garmin-enheter - Tvåspråkig (Engelska/Svenska) vägledning ### Kom igång 1. Ladda ner MitoFlex2 från Garmin Connect IQ Store. 2. Lägg till det i dina aktivitetsdataskärmar. 3. Anpassa inställningar i Garmin Connect för din fitnessnivå. 4. Börja träna och se din prestation skjuta i höjden! **Proffstips**: Para ihop med en pulsmätare. Spåra din MFS-utveckling över tid. Stöd mitt arbete.
